MRI is no better than ultrasound in identifying the presence or size of rotator cuff tears3 but is helpful when evaluating suprascapular nerve dysfunction. It can identify a ganglion compressing the suprascapular nerve in the spino-glenoid notch.
About the organisation
Disorders of the shoulder are common and often disabling. They affect all age groups but are particularly common in individuals who are active in sport, and in work or recreation that involves overhead activities. The clinical tests and imaging modalities used to diagnose shoulder pain have advanced significantly, as have methods to treat shoulder problems. Fortunately, we are moving out of the era of a “black box” for shoulder pain into an era where the condition can be diagnosed specifically and treated rapidly and effectively.
There are actually relatively few diagnoses to make when considering shoulder dysfunction. The shoulder can be too loose – (shoulder instability) or too stiff (frozen shoulder), the rotator cuff can dysfunction or there may be a fracture or arthritis.
